File Access Denied popup when renaming shortcuts for Metro Start Menu

I've been getting a "File Access Denied, You'll need to provide administrator permission to rename this file", popup window even with UAC turned off?
The files in question are shortcuts in the C:\ProgramData\Microsoft\Windows\Start Menu\Programs.
It also happens in C:\Users\User-Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs.
Basically what I'm doing is renaming the title of the tiles/programs displayed on the Metro Start screen.
If there is a better way I'm all for that as having to click continue every time is getting old.

Did you turn uac fully off in the registry - or just using the slider control?

Just with the slider.

So what is the solution for the issue????

Slider is not good enough. Set the enableLUA key in the registry. It will break metro apps, so remember to turn it back on afterwards(if you use metro apps).
